docker拉去镜像时报错，Error response from daemon: Get “https://registry-1.docker.io/v2/“: net/http: request

拉去镜像时的报错信息：
Error response from daemon: Get “https://registry-1.docker.io/v2/”: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

解决方法：
在/etc/docker目录下修改访问链接,如果没有该文件直接创建
输入以下地址
vim /etc/docker/daemon.josn

{
    "registry-mirrors": [
	 "https://docker.registry.cyou",
	 "https://docker-cf.registry.cyou",
	 "https://dockercf.jsdelivr.fyi",
	 "https://docker.jsdelivr.fyi",
	 "https://dockertest.jsdelivr.fyi",
	 "https://mirror.aliyuncs.com",
	 "https://dockerproxy.com",
	 "https://mirror.baidubce.com",
	 "https://docker.m.daocloud.io",
	 "https://docker.nju.edu.cn",
	 "https://docker.mirrors.sjtug.sjtu.edu.cn",
	 "https://docker.mirrors.ustc.edu.cn",
	 "https://mirror.iscas.ac.cn",
	 "https://docker.rainbond.cc"]
  }

保存之后重启服务

sudo systemctl daemon-reload
sudo systemctl restart docker

亲测有效！！！
